SHAFT-HANGER.

Specification of Letters Patent.

Patented J an. 14, 1919.

Application led September 12, 1917. Serial No. 190,892.

resident of Kilbourn, in the county of Columbia and the State of Wisconsin, have invented certain new and useful Improvements in Shaft-Hangers, of which the following is a specification.

This invention relates to improvements in a hanger for shafts of the type used in machine shops for transmitting power to machines of various kinds, and it consists in certain peculiarities of the construction, novel arrangement and operation of the several parts thereof, as will be hereinafter more fully set forth and specifically claimed.

f The principal object of the invention is to provide a shaft-hanger of an extremely simple and inexpensive construction, which shall be strong, durable, and efficient in operation,

and so made that it can be readily mounted in either a vertical or horizontal position, to

properly support a shaft, or in other Words, can be mounted to depend from al ceiling or -elevated support, or to extend upwardly from a suitable support, or if desired, can be mounted on a wall or upright support so as to extend laterally or horizontally therefrom.

-Another object of the invention is to provide a shaft-hanger of the above `described character, the parts of which shall be so made' as to enable them to be adjusted in such al manner as to support the shaft at various distances from the ends of the hanger.

Other objects and advantages of the in-` vention will be disclosed in the subjoined delscription and explanation.

In the accompanying drawing which serves to illustrate an embodiment of the invention,

Figure 1, is a side view of the hanger showing one form of the construction thereof.

Fig. 2, is a view partly in elevation and partly in section, taken on line 2--2 of Fig. 1 looking in the direction indicated by the arrows.

Fig. 3, is a detached perspective view of i one of the supporting bolts for the bearing members for the shaft.

Fig. 4, is a view similar to that shown in Fig. 1 illustrating a modification in the construction of the hanger, and

- Fi 5, is a view partly 1n section and vpa. y `in. elevation taken online 5--5 of Fig.

support may be a vertical one, and that the hanger may extend laterally or horizontally therefrom, or it may be mounted on a support so as to extend upwardly from the latter. As is clearly shown in Figs. 1 and 4 of the drawing, the hanger includes a U-sha-ped yoke, which by preference, is made of piping or tubular material.

Referring now to Figs. 1 and 2 of the drawing it will be seen and understood that the members 9 of the yoke 8 lie in parallel-V ism with one another, and that each of said members is provided in its inner wall `with a longitudinally extended slot 10, each of which slots is provided at suitable distances apart with enlargementsor recesses 11, for the purpose to be presently explained." The free ends of the members 9 are fitted in segmental socket pieces 12, formed on and projected from a base or plate 13 which may be secured to the support 7 .by means of bolts 14 extended through suitable openings 15` in said plate. These openings 15 are shown by dotted lines in Figs. 1 and 4 of the drawings as being slots or elongated openings, and by preference are so made Each of the mem-4 bers 9 is provided near its free end with a transverse opening for the reception of a bolt 16 which bolts are extended through suitable openings in the socket pieces 12 and in connection with nuts 17 on said bolts, serve to firmly secure the free ends of the members 9 to said socket pieces and base. Adjustably mounted between the members 9 of the yoke, by means of a pair of supporting bolts 18 is the bearing for the shaft. This bearing, is indicated as a whole, by the reference numeral 19 and consists of a; pair vof segmental or semi-circular blocks 2O of wood or other suitable material placed with their straightV edges in contact with one an` faces of the blocks 20 each of said clips have.

ing at each of its sides an `apertured extension 23, which extensions are adapted to contact with one another in pairs, so that Athe le, w, r v. openings therein will register with one another for the reception of portionsl of the supporting bolts 18, one of which is located in each pair of the extensions 23 and may ibe -adjustablfy secured therein by means of nuts 24 and 25, one of which `nuts is located below the extensions 23 andthe other one Y'above said extensions as is clearly shown in Fig. 1 of the drawing. Each of the rbolts 18 -hasiatoneof its ends a lateralprojection 25Il which is flattened `as shown in Fig. 3 of the drawing. Each of the blocks 20 of the bearing, is -provided on its outer surface about midway between its ends with a de Apression `or recess 26, which depressions are by preference concave in shape. When the blocks 20 lare placed in their normal positions the depressions y26 therein will be located `dia'metrically oppositeeach other to receive the projections 27 with which the clips 22iare .provided on their vinner surfaces at proper .points to `fit inthe recesses 26 of the blocks V20 ofthe fbearing. By this arrangement it willfgbe seen and understood that as the supporting bolts 18, are screw threaded, `a .nut ,25 may be'screwed onto each of said bolts rtoward the proj ection 25athereion, therefore that portion yof each of said boltsopposite its .projection 25a may be `.passed through the openings in the extensions'23 when another'nut2d may be screwed onto each .of the bolts 18 so as to tightly 'clamp ithe ,clips 22 in .position on .the blocks 20, which bypreason ,of the engagement of the lrec'esses'26 in Asaid blocks with the projections `27 onfthe clips, the said .blocks'will 'be prevented from lturning or slipping out ofthe clips. When thus assembled the projections 2 5a on the bolts 18 will project in opposite directions.` By placing the bearing `finthe 4position shown .by dotted lines in Fig.

l2. vrofjt`he .dra.wing, it :isobvious that the flattened .projections 25a may .be inserted into Y the :slots 1,0of v.fthe members v9 of 4the yoke, iand fmoi'ed `up ordown in Vsaid slots until they .reach 'a Vpair of the enlargements 11 in -Saidgslotsfwhen itis apparentthat by turning the bearing to theposition shown by .continuouslines in Figs. 1 and k2 of the drawing, the .bearing .will be supported at :erprexmefeli' the desired Point'- Sheulf the bearing require further orV nicer adjustmet. as'cabeaccomphshed by turning the nuts V 24: (and ,2.5 on the supporting bolts 148;,"in`th'efproper 'direction to advance or re- V j-.trajet .ii-,hebearing .on said bolts.

Y et

ljigsuieand,v 5 of the drawing, Ihave iillnstrated amodication inthe construction Y of theghangen which.consists in yoinittin'g 'the slots n 10see Figs.' 1 and 2, and in providingV @basement .Welle {olf-dife membeife. @if .the yoke wtha seriesfof openings 28 vlocated in Figs. 1 to 3 inclusive of the dra-wing, with the exception that the supporting bolts of the modified construction are provided each with a lateral projection 29 to enter the openings 28in the members 9 of the yoke, which projections :are by preference cylindrical in shape as shown. When thisniodified construction is employed it will be necessary to lplace the projections 29 on the bolts 18 in the openings 28 of the members 9 of the yoke, before the bearing is assembled or mounted on the said bolt, for itis appar-- ent that the projections 29 could not be inserted into the proper openings 28 therefor, after` the parts of the bearing have -been mounted on the 'supporting bolts.

As the yoke 8 is detachably secured to the socketed parts l12 on the base 13, it is mafnifest that the hanger can be employed for supporting a shaft at v a p oint between pulleys mounted on 'said shaft, by simply detaching the yoke from the lbase 13, then securing the basent the 'proper place toa suitable support, then placing the yoke astride of the shaft and securing the ends of the members 9 to thelbase and then'placing the parts ofthe bearing around the shaft, andV then suitably adjusting the bearing,

Thile I vhave shown the ends ofV theV yoke detachably mounted o'n a base and prefer to so construct the hanger, yet itis apparent Ithat the base and its soeketed members may be omitted andthe 'free ends of the yoke otherwise supported. Y I Y Having .thus fully described kthe l'invention, what I claim as new and desire lto secure by Letters Patent is:
